[linux-6.6.y] x86/mce: Set bios_cmci_threshold for CMCI threshold #281
Conversation
zhaoxin inclusion category: bugfix CVE: NA ----------------- In the Linux kernel, the CMCI threshold is set to 1 by default. This patch prevents Linux from overwriting the CMCI threshold set by the bios. With this patch, the CMCI threshold can be set through the BIOS, which can also avoid CMCI storms, on Zhaoxin/Centaur CPUs. Signed-off-by: leoliu-oc <leoliu-oc@zhaoxin.com>
